I purchased the WRT54G router a few years ago and have been using it as my primary wireless until recently when I upgraded to a 802.11n router.

I have had a lot of experience with Linksys products before and while comparable to Netgear or D-Link, the products still tend to be superior.
The wireless range is pretty good and was even better with upgraded antennas (which can cost as much as the router but if you want long range, go for it).
The feature set is pretty good, with the usual range of wireless MAC filtering, encryption features up to WPA2. Being able to run mixed-mode B-G is also a great bonus for devices that do not use 802.11g.
As a firewall the features such as outbound URL filtering, port forwarding, and connection time limits are pretty standard now.
The biggest downside of this router is that it will start to flake out if persisent connections exceed about 50. This is a known bug, and not an issue with the Linux versions, but when using file sharing in conjunction with a few hosted servers can cause problems without limiting connections. The only way to fix this is a reboot.
Administration is great - a web page interface, with default settings that will get most novice users connected, and enough configurable settings for power users to take full advantage of the features.
